Graphical illustration of the perceptual (generative) model with states x₁, x₂, and x₃. The model parameters ω and |$\vartheta $| impact on the time course of subjects' inferred belief about the states x and are estimated from the individual subject RS data. Circles represent constants, while diamonds represent quantities that change in time (i.e., that carry a time (or trial) index). Hexagons, like diamonds, represent quantities that change in time but that additionally depend on their previous state in time in a Markovian fashion.
